Is it possible to remove the rest of Liberty City (Broker, Dukes, Bohan, & Algonqiun), but leave Alderney, and is it possible to add more land directly onto Alderney, rather than make a separate island?

The Booth Tunnel is guarded by armed officers as construction workers inspect the tunnel's exterior entrance. The tunnel itslef, however, is flooded and barricaded to keep civilians (and the player) from accessing it.

I can imagine armed officers, debris, construction workers, and barricades can be spawned onto the map VIA 3dsmax, but how do you get water into the tunnel?
